This search facility has been designed for users (e.g. agencies, direct clients, organisations) of CIOL members to verify the credentials of any individual member, including Chartered Linguists.

The system only shows members whose membership is "Current", i.e. fully paid-up and with no ongoing disciplinary action. It does not show lapsed or resigned members. 
• Members with multiple entries have memberships at different grades for different languages. 
• Honorary Members (HonMCIL) and Honorary Fellows (HonFCIL) are not listed.
• It is not necessary to complete more than one field.
"CIOL number" is the new, combined membership/Chartered Linguist number, which came into force on 1 September 2016. All members have a CIOL number. Old-style numbers are not searchable but are shown on members' records if they had one.
• If you cannot find who you are looking for and wish to double-check, please call us on +44 (0) 20 7940 3100 (ext. 2) or email the membership team.


Please ensure you spell the member’s name correctly.

You don’t need to add diacritics to search accurately (e.g. entering “Muller” will find “Müller”).

A member’s CIOL number is five digits long.

All members have a CIOL number.
